In a method for producing a high-pressure hydraulic line, a connection fitting (4) is attached to the end of a multi-layer high-pressure hose (5) with at least one reinforcement layer (6, 7) by inserting a section of a reinforced high-pressure hose (5) and one to be joined to it Connection fitting (4) is provided, the connection fitting (4) is placed on the end section of the high-pressure hose (5) and a joining operation is carried out to form a tight connection between the high-pressure hose (5) and the connection fitting (4). The quality of the connection between the connection fitting (4) and the hydraulic hose (5) is determined by at least one connection (12; 16) of a test arrangement (18) having two connections (12, 16), of which a first connection (12) electrically and / or magnetically to the connection fitting (4) and a second connection (16) electrically and / or magnetically to the reinforcement layer (6) or at least one of the reinforcement layers (6, 7) of the high-pressure hose (5), with an electrical test signal is applied, an electrical reaction signal that occurs in the test arrangement is detected and the reaction signal is compared with a setpoint range stored in a memory of the test arrangement (18) for the relevant high-pressure hose connection fitting pairing.
